GUSTAF A. ANDERSON, or'nnnsas CITY, Kansas.

Hoen-courante.

Be it known that l, GUSTAF AgANDERsoN, a citizen of the United States, residing at Kansas City, in the county of 'Wyandotte and State of Kansas, haveinvented certain new and useful Improvements in Hose- Couplings, of which the following isa speciication.

My invention relates to improvements in hose couplings` v The object of my invention is to provide a hose coupling with which connect-ions and Ydisconnections between two sections of hose may be quickly made, and which will permit-relativeretation and effect at the same A.; time af'tightj joint between the two sections which-it connects. j

A sealing ring 5 is-clamped between one an-4 nular member and the ipe section connected thereto and is adapte pi resection. i

n its preferable form my improved couplin is constructed as follows he Iinner annular member 3 is internally 'serewfthreaded at one end, the threaded por tion 'being fitted' to. the externally `screw threaded end `of the pipe section 1. The

member Sis provided with an innerannular.' f flange G'agai'nst which is tightly clamped by y vSpecification of Letters Patent.

the adjacent end ofthe pipe section 1 the annular' peripheral flange 7 provided at one end of the ring 5 the other end of which is preferably tapering and fitted within the adjacent end of the pipe section 2. The sealing ring-5 is preferably eXpansible and made of 'resilient material, such as soft rubber, so

that vwhen there is a water pressure in the coupling thering 5 will expand and bear tightlyagainst the inner wall of thelpipe section 2.

The annular member 3 is provided with a peripheral annular groove 8 anda peripheral annular shoulder or flange 9. The annular member 4 encircles the flange or Shoulder 9 and embraces opposite sides of said ange or shoulder to prevent detachment from each other of the members 3 and 4 while permitting axial rotation of said members relative to each other. In constructing the'coupling the member 4 isvpreferably made as shown in Fig. 2 with an end recess in which the ange 9 is slipped after which the adjacent end of the member 4 is turned inwardly to form an annular'fiange 10 which enters the groove 8, as shown 1n Fi 1 j ne end of the pipe section 2 is provided with two oppositely disposed peripheral shoulders 11 which are adapted to enter end notches 12 provided in one end of the member 4 when the pipesection is 'inserted in said member.` Intermediate the notches 12 in the member 4 are inner peripheral recesses 13 which arevadapted to receive the shoulders 11 when thepipe section has been inserted in the member 2 and rotated to the proper position represented in Fig. 3.

To releasably hold the pipe section 2 against rotation from the locked position justdescribed a lever 14 is pivoted on a pin v adjacent to one end thereof and normally forces theopposite end of the lever into a for engaging the adjacent shoulder 11.

In making a coupling. connection between two sections of hose, the pipe section is in- 'bears against the inner side of the lever 14 v serted in 4the annular member 4 and turned to the position .shown in Fig. 3, at which v time the lever 14 falls to the rear of the ad.

jacent shoulder 11 and prevents retractive.

rotation of the pipe section in the member 4.

To disconnect the pipe section from the member 4 it is but necessary to depress the endof the lever 14 immediately over the spring 17, thus swinging said lever so that the shoulder 11 previously engaged by the lever is freed therefrom, after which the pipe section 2 is rotated until the shoulders l11 aline with the notches 12, at which time the pipe section may be withdrawn from the member 4.

' The members 3 and 4 being axially swiv-v eled to each other the pipe sections 1 and 2.

may freely rotate in either direction any number of times, thus permitting'the twisting inthe hose due to coilingor uncoiling .to be readily eliminated, the water pressure p in the hose suiiicing to eect this resultautomatically when water is turned into the hose.
